Julia Roberts Late Show David Letterman New York pregnant

Is she or isn't she?

Julia Roberts taped The Late Show with David Letterman today in N.Y.C., and the actress did little to dispel the rumors she's got a bun in the oven by wearing a baggy coat and loose-fitting slacks.

The A-lister found herself at the center of baby speculation the other day when a picture of her surfaced looking significantly bigger in her midsection.

She already has three kids and she's 46-years-old, so we doubt she's got another one on the way, but crazier things have happened!

Miss Roberts was just handed a SAG nomination for her supporting role in the Tony award-winning play August: Osage County, so either way, she's got a lot to smile about these days!
